Sean who was originally lowering his head immediately looked up and then turned to a young man who was currently in front of him so that now he who knew this sighed for a moment before finally shaking his head with a wry smile.
"I don't understand everyone, and why should I?!" Sean sighed with both hands tightly clenched, looking at someone who was in front of him at this time with his sharp gaze. "I don't know anything, much less a secret like you said it!"
"You've been with brother David all this time, so it's impossible if you don't know anything about him."
"I'm not like you, Sehan. I'm Sean, and my job is to look after Celine, that's all."
"I saw it all, but all this time I've been silent because I wanted to protect you! Don't you ever think a little bit about me whenever you're not home?! I WAS THE ONE PROTECTING YOU FROM FATHER'S PUNISHMENT!"
